On properties of fuzzy lefth-ideals in hemirings witht-norms

摘要

The notion ofT-fuzzy lefth-ideals in a hemiring is introduced and basic properties are investigated. Using a collection of lefth-ideals of a hemiringS,T-fuzzy lefth-ideals ofSare established. The notion of a finite-valuedT-fuzzy lefth-ideal is introduced, and its characterization is given.T-fuzzy relations on a hemiringSare discussed.
